To all whom it may concern:

Be it known that we, CHARLES T. WEST- United States, residing at St.Louis,"Mis souri, have invented a certain new and useful Improvement inCar-Underframes, of

which the following is a full, clear, and eX- act description, such aswill enable others skilled in the art to which it appe'rtains to 'makeand use the same, reference being had tothe accompanying drawings,forming part of this specification, .in which- Figure 1 is-a planview ofan underframe of our improved construction. Fig. 2 is a longitudinalsection taken approximately on line 2-2 of Fig. 1. Fig. 3 is an enlargedhorizontal section taken through a portlon of the bulling sill at thepoint where one,of the vertical end posts is attached. Fig. 4 is anenlarged cross section taken approxil' mately on line 4-4 of Fig. 1.

This invention relates to that type of'un derframes wherein a doublebody bolster, 'a'

latform frame and a bufling beam are comined preferably in a singlecast-ing and the type of underframe herein shown and described isparticularly adapted for, use in connection with blind end cars,although our invention is, -of course, not confined to this particulartype of cars. y

Our invention is particularly designed to meet the requirements of .aconstruction where it is desirable to increase the strength of old carsby the application of a steel underframe and strong vert-ical endposts.y Ordinarily in the re-building or repair of old cars the endposts can only be applied to the car body by permitting the rear flangesof said posts to 4bear against the outer faces of the end sill so thatsaid posts extend approximately or 12 inches out-ward from the end sill,and 'at ltheir upper ends said posts project bey'ondthe old hood or endor top portion of the car, thus necessitating the replacing of the hoodwhich involves considerable labor and material and expense.

Our invention 1s deslgned to overcome t the objection just noted, andthe end sill of rear portion of the end sill, and thus the outer flangesor edges of 'said endposts do notproject beyond the present limits ofthe hood of the car, and thus it is not necessary F. FREDE, citizens ofthe to re-build the hood and all benefits of strong, deep end posts areobtained.

' Our improved construction permits the retention of the old wooden endsills of the car body, and it is only necessary to notch these woodenend sills at two points and therefore said end sills retain practicallytheir full strength whencombined with our improved underframe and bufferbeam.

To the above purposes our invention con-4 sists in certain novelfeatures of construction and arrangement of parts hereinafter more fullydescribed and claimed.

As shown in the drawings the double body bolster of our improvedunderframe comprises a pair of bolster members 1 united at their.centers by a longitudinally extending member 2 and the ends of saidbolster member 1 are connected by side rails or members 3 which areparallel with the center member 2. The platform frame or extensioncomprises a center member 4 which is formed y integral with the doublebody bolster in alinement with the member 2, and formed integral 4withthe ends of the member 1 to whichthe member 4 is connected are siderails or pieces 5 which are practically continua-tions vof. the siderails 3. Formed in the forward portion of the member 4 is a seriesofpockets 6 adapted to receive the bufling gear. The forward ends of theparts 4 and 5 are united by a horizontally disposed plate orend sill 7,and formed integral with this end sill and occupying a position abovethe plane occupied by the top of said end sill is a buffer beam 8 whichis preferably of the usual box shape, and provided in its front and rearwalls with suitable openings 9 for the buffer stems. Verticallydisposed, horizontally extending webs or flanges 10 areformed integralwith the under sides of the buffer beam 8, end sill 7, platform frameand double body bolster. The body of the buffer beam 8 is extendedrearwardlyl over the top' of the end sill 7 as designated by 11 atpoints equi-distant -from the center of said beam and these rearwardextensions are made for the purpose of accommodating extra wide I-beams12 which are utilized as end posts between the buffer beam and the end'of the hood of the car body. Formed through the top platel of the bufferbeam betweenthe front wall thereof and the rear walls of the extensions11 are'openings 13 adapted to receive the lower ends of the I- beams 12,and formed through the bottom plate of the buffer beam immediately belowthe openings 13 are T-'shaped openings 14 adapted to receive the extremelower ends of the end posts 12. The lower front :corners of the posts 12are notched or cut away so that the front lianges of said posts restdirectly upon the bottom plate of the buffer beam while the rear angesand rea-r portions of the webs of said posts project through theopenings 14.'A Vertically disposedwalls 15 are formed integral with thevtop and bottom plates of the buffer beam immediately adjacent the sidesof the openings 13 and 14, thereby materially strengthening the bui'erbeam at the points in which the openings are formed, and formed on theunder side of the buffer beam in alinementf` of said posts unite withthe hood of the car at the proper points. The wooden end sill of the carbody rests directly on top of the end sill 7 immediately to the rear ofthe buffer beam, and it is only necessary to notch this wooden end sillat two points ,to accommodate the rearward extensions 11,- and thus thefull strength/of the wooden end sill is practically retained throughoutits length.

' The side bearing members used in connection with our improvedunderframe consist of cast metal beams or rails 17, the ends of whlchare provided with integral horizontally disposed plates or lianges 18which are perforated in order to receive rivets or like fasteningdevices by means of which said side bearings are attached to the bolstermembers 1. A car underframe of our improved construction is very strongand rigid, is comparatively light in weight, combines in one casting thedouble body bolster, the platform frame, end sill and buier beam andsaid underframe is particularly adapted for" use in connection with carbodies now -in use, and when applied to said car bodies 'materiallystrengthens the end portions thereof and the end posts which arerigidly'tixed' to the buffer beam are located so as to conform with theend sills and hoodsof car bodies of the presentconstruction.

It will be readily understood that minor changes in, the size, form andconstruction of the various parts of our'improved' underfime can be madeand substituted for those' herein shown and described without departingfrom the' spirit of 'our invention, the

scope of which is set forth in the appendedl i claims.
